On a frigid Monday morning, teenage Helena encounters a new boy named Bobby who claims through telepathy that he loves her and intends to marry her, causing her to collapse in shock while her protective friends confront him. Bobby reveals he is the reincarnation of a past love who traveled back in time from the year 5170 with permission from a time lord named Joshua, having lived for thousands of years in a spiritual realm called Level 5 after a catastrophic AI event in 2120 killed all life on Earth.
